Lots of good info on here for sure. When it comes to the "traditional" aspect of this, I don't see much difference between ILF and normal t/d. Never understood how a bolt and a pin is "traditional" but a bolt and a pin with spring in it isn't.
What I like about LF is that if you want the built by hand "custom" touch, its available, if you want total function, it's available. If you want to mix the two, it's available. If you want Morrison beauty with TradTech functionality and value, no problem. How about a metal riser with Dryad static limbs? That little pin with the spring in it makes all these combinations possible. What if you want (need) a new set of limbs but don't want to (can't) wait six months to get them?
How about little things like switching from split finger to 3 under and your favorite custom is tillered for split? With ILF, no problem...just adjust the tiller. How about those carbons that you just can't seem to get to fly perfectly out of your setup? One size is too stiff and one size is too weak. Why not just adjust your poundage by a couple pounds and dial them in?
I would agree that the there is some really nice ILF stuff being made here by the custom bowyers and I'm betting that it will only get bigger and more popular. The only difference I see is the ability to shoot lighter arrows if you choose to. Companies like Hoyt, TradTech, Winn Winn, and others are quite comfortable with arrow weights in the 6-8 gpp range but I don't think bowyers like some mentioned here would be too comfortable with that, either with their limbs or risers. To some people, especially those that are into 3d and target shooting as well as hunting, that is a drawback.
Although it wasn't really new, DAS re-introduced an old concept to the hunting market with a few new twists. Since then, others have stepped it up in terms of convenience, performance, custom options and availability. I can't wait to see what comes next.
